Application filed August 2G, 1916.

To cZ'Z lwhom 'it m 0?/ Concern Be it known that l, Jarras Lrr'rLn, a citizen of the United States, residing at Bismarck, in the county of Burleigh and State of North lakota, ha ve invented certain new and useful improvements in later-Heaters for Gas or Gasolene Stoves, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved water heater for gas or gasolene stoves and has for its primary objectto provide a very simply constructed and inexpensive device for the purpose of quickly heating the water in a range boiler or tank.

It is a more particular object of the invention to provide a heating chamber mounted for horizontal swinging movement to an operative position over one of the range burners or to an inoperative position at one side ofthe range, said heating chamber being connected by inlet and return conduits to the boiler or tank, such connection being shut olf when the chamber is swung to its inoperative position.

It is another important object of the invention to provide improved means for rctaining the heat contiguous to the walls of the heating chamber so that the water will be very quickly heated to a high temperature.

lith the above and other objects in view, my invention .consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a plan view showing my irnproved water heater employed in connection with an ordinary gas range, the heating chamber being shown in operative position in full lines and in `,an inoperative position in dotted lines;

Fig. 2 is an enlarged vertical section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a section taken on the line 3 3 of Fig. 1.

Referring in detail to the drawing, R designates a gas or oil burning range provided with the usual spaced burners indicated at B, and W indicates the water boiler or tank suitably mounted in spaced relation to the range or stove.

A bracket indicated generally by the numeral 5, is suitably secured to one side of the range R, said bracket having vertically Specification o1 Letters Patent.

spaced arms 6. ln these bracket arms, the upper and lower ends of a pipe or tube 7 are suitably secured against rotation, and this pipe is provided with a central division or partition wall 8 therein, thereby separating the interior of the pipe into two noncommunicating water receiving com aartments 9 and 10 respectively.

rllhe water heating chamber 11 which is preferably of galvanized sheet iron construction and of triangular form in crosssection, is provided in one of its end walls with the vertically spaced nipples 12 and 13. llneh of these nipples has a ring or annulus 1l formed upon its outer end, the bore of the nipple opening through the inner wall of said ring. A gasket 15 is suitably secured within each of the rings 1land also has an opening 1G therein coinciding with the bore of the nipple. The spaced rings 1e are engaged upon the fixed vertical pipe .7 respectively above and below the division or partition wall S therein, and the said fixed pipe is provided with ports 17 and 18 respectively, with which the bores of the nipples 12 and 18 are adapted to register when the heating chamber is disposed in its operative position. Between the rings lil. a spacing collar 1) is suitably fixed upon ythe vertical pipe 7.

To the lower compartment 9 of the pipe 7, a water conducting pipe 2O is connected at one of its ends and has its other end connected to the bottom of the water boiler Vil. A similar return pipe Q1 is connected to the upper compartment 10 and to the top of the boiler or tank.

A sheet metal hood or cover 22 is disposed over the water heating chamber 11 and is provided in one of its end walls with spaced slots Q3 to receive the respective nipples 12 and 13, said cover having limited vertical movement with respect to the heating chamber. The inner walls of this cover Q2 are lined with asbestos or other non-heat conducting material shown at Q4, and the longitudinal end edges of said cover, when in its normal position, project downwardly below the base wall of the heating chamber 11 and are adapted to rest upon the stove or range around the burner B, as clearly shown in Fig. 2. Thus, the heat is retained or held between the walls of the hood or cover so that the walls of the heating chamber 11 will soon become very highly heated.

rthe wall adjacent thereto.

slightly so that it i.. ill not impede this hori- Zontal swinging movement of the heating chamber. AUpon 'releasing the cover, it will. drop downwardly and rest upon the range. ln such movement of the hea ingchambenthc rings or l-l and the gaskets therein are turned upon the iixed pipe 7 so to register the openings in the gaskets and the bores of the nipples l?. and 13 with the ports of the respective vcompartments 9 andjlO. The cold water enters the compartment l0 'through the pipe 20 and passes through the lower nipple 13 into the chamber ll.. vThe burner flame contacting with the bottom wall of the chambei', soon heats the water which rises through the. nipple l2 and the upper compartment v9 of the pipe 7 and the.pipe'orconduit 2l, and is th'us returned to the boiler. llin this manners it will be seen that there is a continuous circulation of water between the chamber and the boiler or tank, the Acolder water-'at the bottom o f the vboiler continuously replacing the heated water in saidk chamber until the entire contents of the boiler is heated to the desired temperature. After heating the water, the hood or cover 22 is lifted slightly and said cover, together with the heating chamber 1l, swung to the dotted-line,` inoperative:v position shown in Fig. l, and in suchsivingiiig movement the bores of the nipples aremoved out of registering relation withvthe ports of the pipe 7 and said ports tightly. closed means of the gaskets 15, thus effectually cutting o the further flow of the water between tho heating chamber and the tank or reservoir.

From the above, it will 'be seen that l have devised a very simple, as well as serviceable rand convenient water heating device for use in connection with gas or oil ranges, whereby water may be very-quickly and highly heated in suilicient quantities for domestic use. The

supportingl bracket 5 may be mounted either upon the frame of the stove or range or upon The water heating chamber l1 can also be made in various Aother shapes than thatillustrated and of any i desired capacity.

l/Vhilehave shown and described the preferred construction and arrangement ofthe several elements herein described, it is to be Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents understood that the invention is susceptible of considerable modification therein and/l, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embot ied within the spirit and scope of the invention as claimed.

Having thus fully described my invention,

what l desire to claim and secure by Letters Patent is l. ln a water heater, a source of heat, a heating chamber mounted for horizontal swinging movement, said chamber being of triangular form in cross-section and having a horizontal base wall, a water supply and means for establishing 'a continuous circulation of water between the same' and said chamber when the chamber is sw ung to an operative position over the source of heat, and a heat retaining hood having inclined walls extending parallel relationV to the top walls of the water chamber and vertical marginal. walls ektending below the horizontal bottom wall of the chamber.

2. ln a ywater heater, a source-of heat, a lined, vertical support havingl separate water receiving compartments, a heating chamber having spaced nipples mounted upon the support for turning movement and communicating-with the respective compartments, a source of water supply, supply and return pipes connecting the same to the respective compartments of said support, and a heat retaining hood extending over the Water chamber andv having` slots in one of its end walls to accommodate the nipples, lsaid nipples limiting-'fthe vertical movement of the hood with respect to the chamber.

3. ln a water heater, the combination with a range having a burner, of a water, heating chamber mounted at one side of the range for horizontal swinging movement to operative or inoperative position with respect tothe burner, a water reservoir, means estab- 'lishing a circulation of water between the reservoir and the heating chamber. when said chamber is in operative position, said circulation being'cut ofiE when the chamber is V`swung to an inoperative position, and a heat retaining hood inclosing said chamber and having limited vertical movement -with A-rcspectrthereto, said hood resting upon the range around the burner thereof when the heating chamber is in operative position.

in testimony whereof l hereunto ailiX my signature in the presence of two witnesses.
